G8 Review - Atmospheric Hazards

What is the difference between hurricanes, typhoons, and cyclones?

• They are different storms

• They have different wind speeds.

• They spin in different directions

• They occur in different parts of the world

What three things does a tropical cyclone need to form?

• Cold water, high pressure, and clouds

• Warm oceans, moist air, and the rotation of the earth on its axis

• Ice, low altitude, and dry air

• Mountains, warm air, and high pressure

What role do warm oceans play in the formation of tropical cyclones?

• Warm oceans provide the necessary energy for the storm to intensify and grow.

• Warm oceans cool down the surrounding air, preventing storm formation.

• Warm oceans create a barrier that prevents storms from making landfall.

• Warm oceans have no significant impact on tropical cyclone formation.

Which best describes the process of a tropical storm forming?

• Warm air rises, then cools down, creating ice storms.

• Cold air sinks, causing evaporation and dry conditions. This cold air spins and creates thunder and lightening.

• Warm moist air rises and cool air comes in to fill its place. The air heats up also rises, cools, condenses, and forms powerful clouds. The storm starts to spin due to the Coriolis Effect.

• High-pressure zones push air downward, heating it up and causing storm formation. Strong wind pushes the air towards land.

Why does the Coriolis Effect cause storms to spin?

• It causes moving air to turn right in the Northern Hemisphere and left in the Southern Hemisphere due to Earth's rotation.

• It pulls storms toward the equator, making them spin.

• It increases the speed of winds as they move closer to the poles.

• It creates a vacuum effect that spins storms on the ocean surface.

What is the definition of 'storm surge'?

• A sudden increase in storm intensity.

• A rise in sea level caused by a storm's winds pushing water toward the shore.

• The electrical charge generated by a storm.

• A rapid drop in atmospheric pressure within a storm.

What is the main cause of water contamination during storms?

• The mixing of ocean water with freshwater sources.

• Increased evaporation of water due to storm conditions.

• Overflowing sewage systems, chemicals, and toxic materials during floods.

• The presence of algae blooms in water bodies.

How do El Niño and La Niña affect the oceans?

• El Niño warms Pacific ocean water ; La Niña cools it

• El Niño cools Pacific ocean water, while La Niña warms it.

How can El Niño impact weather?

• It changes where and how much it rains, which can lead to droughts and floods.

• It makes it too warm to fish.

• Typhoons, hurricanes and cyclones all increase

How might El Niño and La Niña impact tropical storms?

• El Niño can increase the number and intensity of storms in the Pacific, while La Niña might do the same in the Atlantic.

• El Niño decreases storm activity worldwide due to increased ocean temperatures.

• La Niña increases the temperature of the ocean, leading to fewer but more intense tropical storms.

• Both El Niño and La Niña have no significant effect on tropical storms.
